Infections can also cause enlargement of the lymph nodes (glands) as well though these usually enlarge near the source of the infection. You may need to note if there are any skin rashes in the area or urinary symptoms that need assessment. If present, you should consider seeing your doctor. If none are present then you can consider continuing your present course of treatment and monitoring for any changes. I hope this helps
